I was having the same necessity and was ending with a VerticalPanel (inside a Scrollpanel) where I added HTML-instances for every new entry being added. That gave me the ability to e.g. deactivate scrolling allowing the reading of the content (if you do a setText, the browser will jump to the beginning of the text again) and you can delete old entries from the beginning of the list to avoid that the browser will run out of memory if the (let's call it) logmonitor is running for a longer period of time. If you look for log-monitor there even might be a ready to use widget somewhere waiting to be downloaded.

Re: Programmatically Generating Physical Key
Thanks Sumit for getting back on this ! My scenario is something like this - On pressing Ctrl+z/Ctrl+y, browser performs Undo/Redo in RichTextArea, I want to support this functionality in Buttons, So my intention was rather than capturing onBrowserEvents(EventPreviews) just generate ctrl +z/ctrl+y programmatically on clicking on buttons and let them browser to handle. This will remove javascript quirks too. And I didn't find any undo/redo implemenations in RichTextArea. _Anurag On Jan 7, 1:11 pm, Reinier Zwitserloot wrote: > I assume you meant faking the pressing of a key on the keyboard. > > You can't do that directly, no, but you can sort-of call the > keylisteners on any particular object. > > For example, let's say you have a TextBox instance called 'textBox', > and you want to simulate pressing the 'X' button. > > You'll need to do two things: > > 1) Simulate the effect of the X button on the textBox itself, which > means updating the text inside by inserting an X at the current cursor > position. > > 2) Call all keyboardlisteners on textBox. > > #2 can be done with some technically nonsupported hackery - each > implementation of SourcesKeyboardEvents in GWT at least has an > internal private object of type 'KeyboardListeners', called > 'keyboardListeners'.

Hosted mode rendering differently when compared to compiled build.
I have a very simply app that just has a StackPanel. When I look at it in the hosted mode the font is huge. When I compile and put it on a server the font renders smaller. I have checked the server version with Chrome, IE7, and Firefox 3. All 3 of these display it the same way -- which is the actual way that I would like it. How do I get the hosted version to work?

Re: Printing Gchart
Couple of more remarks on printing GCharts that may be helpful. The graphical part of a GChart (unless you are using the optional bolt- on canvas line curve capability) is simply a bunch of images absolutely positioned within a box (via AbsolutePanel). So it seems reasonable that this collection of images should act very similarly to a single image chart on the page from the point of view of printing. Thus there is no logical reason you should not be able to print a page containing a GChart just as easily as you could print a page containing an image-based chart. In theory. Now, under normal circumstances, all those images are the same single 1x1 px blank gif. and the background and border and size are manipulated to produce the rectangles of the chart's parts. If this use of image backgrounds is a problem during printing, GChart has methods that allow you to specify a non-blank default image, plus a different image for each curve. These methods are setBlankImageURL and setImageURL, respectively. and could be used to effectively replace the background color with a real image color (assuming the use of image background colors presented a problem during printing, as it can in FF2). Here are the javadoc links for these two methods, for reference: http://gchart.googlecode.com/svn/trunk/doc/com/googlecode/gchart/client/GChart.html#setBlankImageURL%28java.lang.String%29 http://gchart.googlecode.com/svn/trunk/doc/com/googlecode/gchart/client/GChart.Symbol.html#setImageURL%28java.lang.String%29 For example, the "dropped axis lines during printing" you mentioned might be corrected by passing a 1x1 px black GIF to setBlankImageURL and various 1x1px colored images to setImageURL to define each curve's "inside" color instead of the usual use of setBackgroundColor (I've not actually tried this, but it should work). The other part of a GChart is the text. These are placed within single- celled tables (for alignment purposes) and those tables are absolutely positioned on the same box. Again, I don't see why this should be significantly different than printing an image-based chart, either (the alignment techniques are--over a reasonable range--font-size independent). HTML and widget-based annotations and such are the wild-cards, opening it up to just about anything. But, presumably, if you built the HTML/ Widget and wanted to print it, you'd be responsible for that (the same table-based aligned positioning used for text is used for HTML/ widgets, so they should stay in appropriate positions on the chart). Unfortunately, I have zero practical experience building printable web pages so all this is just educated guess work; if anyone has real experience with printable pages and is willing to share that experience to help improve GChart's "printability", I'd appreciate that.

How to wait until the response from the server?
Hi, I am using GWT forms to do file uploads. In one of my cases i want to validate the name given in the Textbox of the form. To validate the name i have to request the server for the names available already. To validate this inside the FormHandlers OnSubmit method i request the server and on invalid name i cancel the form submit.

Re: Restoring focus to the element after closing dialog box
The thing is that the show/center method of the DialogBox is called from many places in the application. And, I do not wish to make changes in these many places (for implementing the solution mentioned above) . So, I thought if we could figure out the element on whose event the dialog box's show was invoked, it would be nice. Sounds a bit far-fetched, but if there is some other way to accomplish this, please suggest. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: gwt-ext similar
Well, there's Ext-GWT (also referred to as GXT). The plus is that it is written entirely in Java. GWT-EXT are JSNI wrappers for Ext-JS. The negative is that there is near-zero documentation (and mostly insufficient code-comments) for it. Basically you learn it by looking at source code for the demos or you pay the one developer thousands of dollars to come teach you. This is very unfortunate because in addition to the GUI components there's fairly neat and robust MVC framework. But you'll spend a lot of time trying to figure it out if you don't pay them to come teach you about the framework. It's a bit buggy, but if you post a bug in the support forums, they tend to get fixed very promptly but you can only get the fix quickly if you pay for support/license. But maintenance releases seem to come out very frequently (like every 4-5 weeks or so.) The component library reasonably robust, but chances are you'll find something you want missing. Summary: Except for the gaping absence of documentation, it's pretty good. But you have to take that into account as you'll either pay thousands to learn it or spend hours doing what is essentially "reverse engineering" it.

app renders in different sizes on different computers
I have created an application that renders fine on my laptop. However, when I build this application on my desktop computer everything comes out much larger. I think the problem is that the fonts are larger on the desktop. This has impact on my layout -- for instance it forces some text boxes to be 2 lines, instead of 1.

Need opinion on design idea
I am thinking about a charting app that will use jfreechart on the server side (I need PDFs and other server side output anyway) and GWT + Canvas on the client so that users can do fancy things like curve fit in the browser. That means that when the client asks the server to render a chart, the client needs to get back a png and also some data (like scaling info, etc). I can of course do 2 rounds trips but I am thinking of combining it into one rt. The idea is that the server response is an image/png but also sets a nonpersistent cookie in the header that encodes the data I need. The gwt app disassembles the cookie value (perhaps it is even json). If the cookie would be too big (unlikely), the cookie value becomes a message to the client that it needs a dedicated rt. Does anyone see a problem with this? Any thoughts are appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Integrating other frameworks into hosted mode
Hi Joe,
Alternatively, you can use hosted mode with the -noserver option to use your
own backend to produce and serve your HTML files. GWT hosted mode will still
work to debug your GWT client-side code as well.
Using hosted mode with the -noserver option:

Re: [gwt-contrib] Call for critical 1.6 bugs
Well, my own wishlist includes Issue #1032, http://code.google.com/p/google-web-toolkit/issues/detail?id=1032. It only effects Maven users, and is somewhat mitigated by the GWT maven plugin, but it is an annoyance because GWT unit tests cannot run inside of the standard maven test harness, which impacts down-the-chain tools like CI servers, report generators, etc. For example, we use TeamCity as our CI build server, which keeps historical timeseries for each unit test, and provides graphs, even performance regression data, but because of #1032, we have to mock out alot of GWT and use TestCase instead of GwtTestCase. I don't know if this will be mitigated by OOPHM or Jetty inclusion. Java 1.6 support on OSX would be nice as well, but I assume this is pending OOPHM and the jettisoning of SWT. -Ray On Wed, Jan 7, 2009 at 2:48 PM, Scott Blum wrote: > Hi all, > We've narrowed down the set of bugs we'd like to fix for GWT 1.6.

Has anyone used Google streetview in GWT?
Hi folks, I am currently using the Mapitz GWT Google Maps bindings (http:// sourceforge.net/tracker/?group_id=169331), because I'm still on GWT1.4 (yeah, I know, I know). When we upgrade to 1.5, I plan to use the Maps API provided by Google: http://code.google.com/docreader/#p=gwt-google-apis&s=gwt-google-apis&t=MapsGettingStarted But I noticed that that even the Google Maps API doesn't support the Maps Streetview: http://code.google.com/apis/maps/documentation/services.html#Streetview I submitted a request to the issue tracker: http://code.google.com/p/gwt-google-apis/issues/detail?id=228 But I was wondering if anyone had had any luck in integrating streetview into a GWT application? It looks simple enough to do plain old JSNI, but I thought it was worth asking. I looked on both the maps and gwt google groups for any reference to streetview and GWT and found nothing.

complex widgets in scroll table cells
I want to display 2 widgets (for example, HTML and a button) in a
single cell of the ScrollTable (in the gwt incubator). I enclosed the
2 widgets in a HorizontalPanel and then added the panel to the
ScrollTable using setWidget(row, column, widget). This displays what
look like partial borders (but are not) -- thin gray lines on the
bottom and right of both the HTML and the button. Is there a better
way to do this?
ScrollTable table;
HorizontalPanel p = new HorizontalPanel();
p.add(new HTML("foo"));
p.add(new Button("press here"));
table.setWidget(1, 2, p);

Using Window Alert inside of Asynch GWTTestCase
Related threads here due to dumb 60 day rule: http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/7be51fdddafa219b/ http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/2c182159532c4aa4/ I've found some weirdness when running an Asynch Test using GWTTestCase inside of eclipse. Essentially, one of my classes under test makes a call to Window.alert(as a response to the Asynch response), which was actually getting shown on my system -- but often shown behind the eclipse window so I would see it. As such, a lot of my tests timed out. As an aside, I also wasn't calling timer.schedule with enough time for my server side services to start, so that caused test assertion failures. When I finally commented out the call to Window alert and got the timing right on my timer.schedule(...) and delayFinishTest(...) the test ran fine. Of course, I had to come up with a different way to test my response. In the first thread above, some suggests are made to get around this. My thought is just to find some other modal popup and use that instead of Window.alert.

Unable to run GWT + Flash on 64bit Linux
Hi there, I'm running GWT on my 64bit Ubuntu 8.10 dev box with a 32bit jvm installed and it works just fine. But all this changes when I want to use (the recently released Google Visualizations for gwt[1], as some of its charts require Flash (applies for all other flash components as well). So I went along and installed the Adobe Flash player. This works fine when I compile and deploy my app but it does NOT work at all in the hosted mode. The hosted mode browser still thinks that Flsah is NOT installed. I think it's because the 32bit hosted browser does not work with the 64bit flash. Do you have any ideas how I can get this setup running? thanks for all suggestions!

Re: generator for Nokia S60 webkit browser
Hi Peter, As far as I know, if the mobile browsers are built from Mozilla and/or WebKit builds, your GWT application should work on them. However, you may want to reconsider the style and positioning of your application, or perhaps even create a lighter version of your application, based on the browser you're running on and the resources available. I would also double-check the following two points: 1) Which phone are planning to support in specific? Which build is it using? Check if the build is in the list of supported browsers (link below). GWT Supported Browsers: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=FAQ_CurrentlySupportBrowsers 2) Test your application on the mobile browser thoroughly. There may be slight differences in the mobile browser that could break certain UI widget implementations, especially if it's using a custom build, in which case you can create your own specialized widget and plug it in via a deferred binding rule. Hope that helps, -Sumit Chandel On Fri, Jan 2, 2009 at 10:49 AM, Peter Ondruška wrote: > > Dear All, > > as mobile phone browsers are getting better and better (faster with > more memory, etc.) I am wondering if there is any way to have pages > generated for those browsers found in Nokia S60 mobile phones.

So is that means in order to retreieve data from database via ibatis,
I have to creat a RPC? or can i call the object/classes from

Re: How to debug serialization issues?
I override onBeforeRequestDeserialized and onAfterResponseSerialized in my servlets to view the raw data being passed in RPC. I have also used HashSet with generics and do not generally have problems. Once, I think it was in an earlier version of GWT, I needed to add any objects that I used generically to a fake method in one of my services. So if the was Set and Set I would add workaround (Foo arg0, Bar arg1) to any of my remote services. This got around the problem.

doc-1-5&s=google-web-toolkit-doc-1-5&t=RefJreEmulation) and objects
which are in your client package.
You probably want to move this to your com...server package instead.

Re: GWT project creation indefinetly creates folder recursively
I experienced this same problem using the latest GWT (1.5.3) for windows and Eclipse Ganymede. I also followed the GWT instructions for creating a brand new GWT project using Eclipse. The project name used in both the projectCreator and applicationCreator scripts was the same. After attempting the import of the new project into Eclipse, I found the infinitely recursive folder chain with projectName \projectName\projectName\projectName\... inside of the Eclipse workspace. Hopefully someone knows the solution to this problem. It is very frustrating... BTW, the too-long filename fix is to go down into the projectName folders and share a folder way down in the path with full permissions. Then map a drive to that folder. This will shorten the path so that you can work with it. You may have to do this more than once. You can also rename the folders to a single letter to shorten the path. I was able to manually delete it using the above methods. On Jan 5, 12:37 pm, TBirch wrote: > I have had this happen to me twice lately trying to import an existing > project into eclipse.

How to debug serialization issues?
How do you guys go about debugging serialization issues? I am using GWT 1.5.3 and my GWT client is sending a DTO to the server. If I do a Log.debug() just prior to the call to the server, I see all of my data in my DTO. However, when I do a log.debug() on my DTO in the GWT-RPC service, some of my data is missing. I have read through forum posts, etc... but I feel I don't have the necessary tools to debug the problem. The data that appears to not be serialized is a Set (implementation is a HashSet) off of my DTO. Both the DTO and CustomClass are marked Serializable, I use generics for the Set. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Problem building GWT with JPA annotations using Ant
Hi,
My application builds and works fine in hosted mode, but I am having
trouble getting my application to compile using Ant. Im using GWT with
hibernate4gwt and JPA annotations, so my gwt xml inherits the
following:
In my domain classes I have many JPA annotations e.g:
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import net.sf.hibernate4gwt.pojo.java5.LazyPojo;
//I am using GXT also, these are to do with that
import com.extjs.gxt.ui.client.data.BeanModelMarker;
import com.extjs.gxt.ui.client.data.BeanModelMarker.BEAN;
@Entity
@Table(name="Contact")
public class Contact extends LazyPojo {
...
}
In my build.xml i have included the following in my class path:
When i try to build, the gwt compiler complains that it cannot find
the JPA annotations classes:
[echo]
[echo] GWT Compiling : com.
[echo]
[java] Processing types in compilation unit: file:/C://
domain/Contact.java
[java] Found type 'Contact'
[java] Resolving annotation '@Entity'
[java] [ERROR]
[java] java.lang.ClassNotFoundException: javax.persistence.Entity
So I am thinking its a class path error, but I am not sure what I need
to add in to make it build properly.
Can anyone help? Thanks
Chris

Re: Get file from server with GWT-RPC
Gregor wrote "if you want to create a directory somewhere else on the

You can add your external directory to tomcat's path. So basically D:
\images could be pathed to localhost:8080/YourApp/images
Then you can access them very easily using GWT by creating an Image
object and calling setURL("images/mycat.jpg");
Look at this to set up your path:

Re: same-origin security restriction
The light bulb finally lit for me. There's browser security rules in place that only allow Ajax to communicate with the same server as the main page. If GWT hosted mode allowed it then in the future when you deployed to production your app wouldn't work. I'm going to change my implementation to have the external data sources route through the server, but may need to add load balancing because of the extra load now on the server. Nothings ever to easy. On Jan 6, 1:10 pm, Scooter wrote: > Please allow this to either be a configurable option or a prompt when > accessing external URL.

Re: Best way to add App configuration properties
Gregor,
I was able to get around it by what Joe Cole mentioned above by just
overwriting the GWT applications generated web.xml. It works fine. I
even created a subdirectory called lib under WEB-INF and put my third
party server side JARs there. The seems the way to go if you need to
start up singletons when tomcat starts or need env properties in the
web.xml

Re: Pbm with PushButton and Images
In fact this problem appears when I run the code in hosted mode.
I've just notice that the same code once compiled and deployed on a
tomcat works fine.
Is there a known bug with hosted mode ?

Re: Compiling a single Java class to a plain JavaScript file
rapodaca: The GWTCompiler is simply what drives the myProject-compile command; it does the same thing (translates a whole bunch of things into a single JS file), so I doubt its what you're looking for. What you want can't really be done. Java isn't javascript. Take your example just to illustrate the problem here: How would that even translate to javascript? Javascript doesn't have classes. It has prototype based inheritance. Here are your fundamental problems: 1. Javascript's namespacing and object model is so different, that GWT internally generates completely different and unwieldy names for objects and classes. These names are then mangled to unrecognizable shortcodes to reduce the size of the output JS. So, your public void hello method is either going to be called: "com.mypackage.Hello::talk ()" (yes, including closing parentheses to indicate that this version takes no parameters; unlike javascript, in java two methods with the same name but different parameter lists are completely separate, in javascript you can't do that), or it's going to be called something small and effectively random, so something like 'xYq' or some such. There's no code to pick a sane name for interaction, so nothing there that would even think to generate just a function called "hello". 2. There's a base set of functions that all GWT projects start out with. The GWT compiler assumes this basis is there. 3. GWT does something called platform targeting. That's why it generates a number of JS files - one for each target platform. Out of the box, there are already multiple platforms (1 for each major supported browser, so there's an Opera, an IE, a Gecko, and a Webkit). I'm not entirely sure but I believe the base, talked about in #2, is already written specifically for each target browser platform. If you are in the market to build such a tool, The GWT sources are a great place to start, but unless you're willing to dig in for a few weeks and do a lot of dev work, I don't think GWT can do what you want. NB: I'm not an expert on the GWT internals so I might have made a few mistakes, but I'm fairly sure the above is true. #1 is certainly true, and already a big deal for you.

Re: Programmatically Generating Physical Key
I assume you meant faking the pressing of a key on the keyboard. You can't do that directly, no, but you can sort-of call the keylisteners on any particular object. For example, let's say you have a TextBox instance called 'textBox', and you want to simulate pressing the 'X' button. You'll need to do two things: 1) Simulate the effect of the X button on the textBox itself, which means updating the text inside by inserting an X at the current cursor position. 2) Call all keyboardlisteners on textBox. #2 can be done with some technically nonsupported hackery - each implementation of SourcesKeyboardEvents in GWT at least has an internal private object of type 'KeyboardListeners', called 'keyboardListeners'. While its private, you can still get at it via JSNI (look that up) which doesn't know about 'private' and thus allows it. Once you have the keyboardListeners, which is really just an ArrayList, you can loop through them and fire the appropriate call (e.g. onKeyPress) on all of them. The reason GWT doesn't support this directly is because javascript doesn't support it either. GWT isn't magic; it cannot make things that are impossible on the target platform possible.
